For this reason it is not allowed to use this system on public roads in Germany and also in some other countries, this applies as well to cat spare pipes (test pipes) and sports cats. Please respect the legal requirements in the respective country. Avoid reving while the vehicle is not moving, since the large flames that come out, could be a cause for the vehicle to burn! Sport exhaust systems which are not allowed on public streets, are meant to be used exclusively for sport racing purposes and on private racing tracks. The use on public roads is done on one's own risk. Before the exhaust system is installed, the buyer must ensure that the use of the exhaust is allowed in their corresponding country.
